"isolated_dwelling" is almost never the correct tag for places in the United States. If you think you've found one while cleaning up GNIS, it's probably either a former town, a former railway stop, or you need to look around to find the rest of the hamlet.

Please don't glue unrelated objects to roads like you did with Town Square Park here. It makes it difficult to modify the roads later, such as when splitting one to add lane information or speed-limit changes.

If it's got a well-defined flow direction, then "intermittent stream" seems reasonable; if it's just a low spot that collects water, then I don't know how I'd tag it.

A cycleway that's also an intermittent stream? Is this a tagging mistake on your part, or a design mistake on someone else's? way/634162906

You added two houses both numbered "4612 West Elderberry Avenue". Was that a mistake?

Cheney? I think your aim's a bit off.

Thanks for the addition.

It's better to put address points on the actual building than on the street: this way, more sophisticated routers can do things like say "your destination is on the right", or find a walking route that involves fewer street crossings.

It's easy to do: simply start editing, right-click on the address point, and select "Extract" (the third item from the top of the menu). Then move the point to the correct location and click to set it down.

The Wikidata item you linked to is about the tribe, not the reservation.

When was that designated WA-907? The state Department of Transportation doesn't seem to know anything about it.

Why did you delete the Mountain Standard Time zone?

The map isn't updated at all zoom levels at the same time. The higher zoom levels usually sync up in an hour or two, a couple days at most, while the lower zoom levels can take longer (when I was mapping some farmland around Spokane, it took nearly three months for it to show up at the "all of Eastern Washington" zoom level).

"amenity=school" doesn't seem right for something that isn't actually an educational institution. "landuse=governmental", perhaps?

Is there a reason why you changed I-90 Business from a route to an administrative boundary?

Welcome to OSM!

The common practice when mapping schools is to put the name only on the school grounds, and leave the school building unnamed unless it has a name distinct from that of the school as a whole.

Did you intend to turn a couple stretches of George Washington Way into barriers?

"Living street" is pretty much a purely European concept. If you find something elsewhere that looks like a living street, it's probably a driveway or an ordinary residential road.

Is this really a worthwhile thing to do? Sure, it's typographically better, but nobody's got an en-dash on their keyboard. Someone searching for "Croton-Harmon", for example, had better hope that the search engine understands that all short horizontal lines are equivalent.

Is this really a stretch of one-way service road? It doesn't look like it in aerial imagery.

Wouldn't that be a not-a-building?

Whose park is that? It's not one of the ones on the city's list.
